Patented sept. 17, 1907.

Application tiled November 24.1906. Serial lo. 844,828.

To all whom it may concern:

lle it known that l, ALMEnoN E. GALKINs, a citizen` and use the same.

My invention relates to new and useiulimprovements in motors and more particularly to that class adapted to be used for propelling boats, automobiles, air ships or the like and my object is to provide a motor oi this class which will propel the article to whichfit is attached without employing the usual form of gearing or propellers.

A further object is to provide a motor of this class whereby the usual form of reciprocating piston head is dispensed with and the atmosphere and water utilized to forni one end of `the combustion chamber.

Other objects and advantages will be `hereinafter referred to 'and more particularly pointed out in the claims. i

In the accompanying drawings which are made a part of thisy application, Figure l is a sectional view through my improved form of motor and one end of a boat showing the motor applied to use thereon. Fig. 2 is a sectional view of a still further modified form oi motor.

For convenience of illustration I have motor applied to use upon a boat although it will be understood that it may be employed in connection with any form of vehicle requiring a motor to propel the f Balme. l

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, l indicates a'boat which may be oi the usual or any preferred form, in `the rear end of which and vadjacent the bottom thereofv is disposed my improved orm of motor, said motor comprising a hollow cylinder 2, which is opened at one end and provided at its opposite end with a head 3.

Any suitable form of packing may be employed for preventing leakage around the cylinder and in this instance I have provided the outer periphery of the cylinder with a flange 4, between which and the adjacent portion ol': the boat is interposed a packing 5 and by which means the water is prevented from entering the boat around the cylinder.

Disposed above the cylinder 2 and located at any suitable point in the boat is a tank 6 in which is adapted to be disposed any suitable combustible material such as vaporized gasolene, alcohol or like material and the tank is connected with the inner or closed end of the shown the 'move the pin from engagement cylinder by means of a feed pipe 7 at a point within the length of which is disposed a `valve 8 so that the combustible material may be shut off from the engine when desired.

Disposed within the cylinder 2 and at any suitable point, is a plug 9 with which is adapted to cooperate a longitudinally movable' ypin 10, the pin and plug forming opposite poles of an electric circuit so that when the pin 10 is directed into engagement with the plug 9 and the circuitthen broken, a spark will be formed which will` ignite the gases within the engine, the plug and pin being connected to any suitable'source ot' electric currentsuch as storage batteries l1, the plug 9, being connected to one pole of the batteries by means of a wire 12 while the opposite pole of the batteries is secured to a head 13 on the pin 10 by means of a wire 14 so that when the pin is in engagement with the plug, the circuit through the batteries will be comlpleted.

The pin 10 is disposed through a stutliing box 15 and is surrounded by a spring 16 which is disposed between the stung box 15 and the head 13, the spring normally vholding the pin 10 out of engagement with the plug 9.

It is mydesire to employ any convenient device for successively directing the pin 10 into engagement with the plug 9 and for convenience of illustration I have shown a cam 17 which is mounted upon a shaft 18, said shaft and cam being rotated in any suitable manner so that when the lip 19 of the cam is directed against the head 13 of the pin, said pin will be directed into engagement with the plug 9 and as soon as th'e lip has passed by the head 13, the spring 16 will quickly rep with the plug thereby causing a spark. l "lli While I have shown the motor as disposed entirely below the water line I desire it tolbe understood that if deemed advisable the closed end or the cylinder imay be disposed above `the water line in which event the combustion-material will be directed into the upper end of the cylinder by any suitable means other than gravity'. It will also be seen that if desired the motor may be placed entirely outside ofthe boat by securing the same to the rear end thereof or other convenient point.

In Fig. 2 the interior of the cylinder 2 is provided with a circumferential shoulder 20 which is located near the closed end of the `cylinder and is provided upon one side with a tapered seat 21 with which is adapted to coperate a conical valve 22 which issupported within the cylinder by means of a stem 23 extending through a suitable bearing in the head 3, the outer end of the stem'h23 having a head 24 thereon. In

. order to normally hold the valve 22 upon the seat 21 I dispose a spring 25 around the stem 23 and between the heads 3 and 24 and by this construction it'will be seen that the charge of explosive material is retained within a chamber 26 at one end of the cylinder 2 and the water is prevented from entering said chamber by means of the valve22. By this construction it will be seen:v that when the explosion is made the valve 22 is moved longitudinaily, thereby allowing the force ofthe explosion to pass through the cylinder 2 and against the volume of water and as soon as the force of the explosion -lis re' moved from the valve 22 the springZowill immediately thus excluding the water.

return the vvalve to its seat from the explosion chamber.

and economical motor for driving a boat or other lvehicle andone Wh'erein'lthe volume of water or atmosphere .is employed for forming oneI end ofthe combustion chamber. the Weight of the Awater oratmosphere serving to drive the boat or vehicle'forward when 4the explosion is directed against the same iand Ait will further be' seen that when the explosion occurs more or less of a vacuum will be formed in the cylinderthereby preventing a4 rapid entrance of the water andgiving' the explosive material time to enter the inner end of the cylinder.

What I claim is: I f 1. In a motor for boats the combination with a bont having an opening in the stern thereof; of a cylindrical lbe disposed through said opening, a peripheral flange on said cylindrical tube adapted to prevent longitudinal movement of said tube, a gasket interposed between said It will lth'uslbe seen that l a very n. feed tube for said cylindrical peripheral flange und the body ot the boat. gas communicating with the closed end oi' tube, 'und means to intermittently cause a spark in said.
